Abstract
Vorrichtung, Dadurch gekennzeichnet, dass die Form der Vorrichtung ein seitliches Schwingen der Kette in zumindest eine Richtung durch zumindest eine Fläche minimiert, sowie die Schwingungen der Fahrradkette in Richtung der Strebe durch zumindest eine Fläche minimiert und dabei ein offenes Profil aufweist und die Kette nicht gänzlich umschließt, Device, characterized in that the shape of the device minimizes lateral oscillation of the chain in at least one direction through at least one surface, and minimizes the vibrations of the bicycle chain in the direction of the strut through at least one surface and has an open profile and the chain is not entirely encloses,
Description
Stand der TechnikState of the art
Zumeist erfolgt die Kraftübertragung bei Fahrrädern über eine Fahrradkette. Dabei verläuft die Kette über zumindest ein Kettenblatt, das direkt mit der Kurbel, die wiederum die Pedale aufnimmt, verbunden ist. Sind mehr als ein Kettenblatt vorzufinden, spricht man auch von Mehrfachantrieben. Die Kette läuft zur Kassette, die am Hinterrad des Fahrrades angebracht ist, hin. Über die Kassette finden Schaltvorgänge statt, hier befindet sich auch das Schaltwerk. Die Kette wird über die Kassette durch das Schaltwerk geleitet und zurück zum Kettenblatt.Most bicycles are used to transmit power via a bicycle chain. The chain runs over at least one chainring that is directly connected to the crank, which in turn picks up the pedals. If there is more than one chainring, one also speaks of multiple drives. The chain runs towards the cassette, which is attached to the rear wheel of the bicycle. Shifting operations take place via the cassette, the rear derailleur is also located here. The chain is routed via the cassette through the rear derailleur and back to the chainring.
Das Hinterrad des Fahrrades wird über Streben mit dem Hauptrahmen des Fahrrades verbunden. Diese Streben werden zumeist in Kettenstrebe und Sitzstreben unterschieden. Im Folgendem sind Sitzstreben und Kettenstreben unter dem Begriff Streben zusammengefast. Die Streben unterscheiden sich zumeist von Hersteller zu Hersteller von Fahrrädern und darüber hinaus auch zumeist in den jeweiligen Modellen der Hersteller in ihrer Form.The rear wheel of the bicycle is connected to the main frame of the bicycle via struts. These struts are mostly divided into chain stays and seat stays. In the following, seat stays and chain stays are grouped together under the term struts. The struts mostly differ from manufacturer to manufacturer of bicycles and also mostly in their shape in the respective models of the manufacturers.
Daneben sind an Oberflächen der Streben des Hinterbaus des Fahrrads oft zumindest teilweise vom Hersteller gummierte Flächen oder Elemente angebracht, die einen Kontakt der Kette mit dem Fahrrad verhindern sollen.In addition, surfaces or elements that are at least partially rubberized by the manufacturer are often attached to the surfaces of the struts of the rear structure of the bicycle, which are intended to prevent the chain from contacting the bicycle.
Daneben sind ebenfalls spezielle Vorrichtungen bekannt, die die Kette vollständig umschließen und eine Führung der Kette ermöglichen, so dass der Kontakt der Fahrradkette mit den anderen Teilen des Fahrrades minimiert wird.In addition, special devices are also known which completely enclose the chain and allow the chain to be guided so that contact of the bicycle chain with the other parts of the bicycle is minimized.
Problemproblem
Besonders bei Fahrten über Unebenheiten, zum Beispiel im Gelände, gerät die Kette in Schwingungen und kann durch Kontakt zu anderen Teilen des Fahrrads Geräusche erzeugen. Bestehende Lösungen weisen jeweilig Probleme auf. Die im Stand der Technik beschriebenen Gummierungen auf den Streben des Fahrrads verhindern nicht das Schwingen der Kette an sich. Die im Stand der Technik beschriebenen Lösungen, die die Kette gänzlich umschließen, sind jeweils nur für eine bestimmte Übersetzung ausgelegt und für Mehrfach Antriebe zumeist ungeeignet.The chain starts to vibrate, especially when driving over bumps, for example off-road, and can generate noises when it comes into contact with other parts of the bike. Existing solutions have problems. The rubber coatings described in the prior art on the struts of the bicycle do not prevent the chain itself from swinging. The solutions described in the prior art, which completely enclose the chain, are each designed only for a specific translation and are mostly unsuitable for multiple drives.
Vorteile der LösungAdvantages of the solution
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Vorrichtung bereitzustellen, die die Schwingungen der Kette minimiert, den ungewollten Kontakt der Kette zu anderen Teilen des Fahrrades verhindert und gleichzeitig auch für Mehrfachantriebe funktioniert.The invention specified in claim 1 is based on the problem of providing a device which minimizes the vibrations of the chain, prevents unwanted contact of the chain with other parts of the bicycle and at the same time also works for multiple drives.
Die Erfindung ermöglicht durch ein offenes Profil, das die Kette nicht gänzlich umschließt, eine individuelle Ausrichtung und Positionierung auf den Streben des Fahrrades. Durch die spezielle Form der Vorrichtung ist eine individuelle Anpassung an unterschiedliche Formen von Streben möglich.The invention enables an individual alignment and positioning on the struts of the bicycle thanks to an open profile that does not completely surround the chain. Due to the special shape of the device, an individual adaptation to different shapes of struts is possible.
